Mathematical modeling and simulation of modern cars in the role of stability analysis

Abstract

In India Automobiles provide a vital infrastructure for the growth of industry and agriculture. Human civilization has inevitably relied on substantial movement of passengers and goods in a speedy manner and the volume of this has gone up enormously with massive rise in population and economic activity. The demand of higher operating speeds, greater axle loads, better riding comfort and more running safety has attracted the attention of professional talents to give a serious thought to the problem of vehicle system dynamics and to devise ways and means to achieve the above requirements through effective methods. At present, the researchers are trying to develop mathematical and computer models, which not only provide a more exact simulation but enable studies to be carried out on stability or response, comfort and optimization of the design characteristics of various components of the vehicle system. Vehicle dynamics, stability deals with the study of vehicle in motion under the action of various forces. Any vehicle comprises of linear as well as angular movements along and about the three mutually perpendicular coordinate directions x, y, z. The linear movements are longitudinal, lateral and vertical displacements and the angular movements are rolling, pitching and yawing respectively for x, y, z directions.
